A very convenient function would be to be able to connect the projector to an Android smartphone, to show a presentation or to see the latest photos we took on a larger screen. Not many users know how to connect the two devices and that is why I would like to show you step by step below how to connect projector to Android smartphone.

How to connect projector to Android smartphone

The methods, of course, are different, and among the different solutions you can choose the one that best matches your needs. You will find simpler methods or more complex methods, it also depends on the characteristics of the projector, whether or not it is equipped with a WiFi connection, for example. Let's go now to see the different methods.

Wireless smartphone projector connection

This is the best and easiest solution to connect an Android smartphone to the projector. Many companies that make projectors have also created the app that allows connection with the smartphone using the Bluetooth or WiFi connection. For this reason, the first thing you should do is check if for your projector equipped with WiFi or Bluetooth and if the official app that allows this connection has been released. You can check both with a search on the Google Play Store and by checking on the projector's official website on the product and model web page. Here are some apps related to some projector models that you can download from the Googlr Play Store:

CASIO | C-Assist

RICOH | RICOH Smart Device Connector

OPTOMA | Optoma Projection Mapper



If your projector does not have an official app, the second best solution is to use the Chromecast device made by Google (costing 39). If you already have a Google Chromecast, just connect it to the projector's HDMI input and use the WiFi to transmit what you see on your smartphone to the projector, using the Chromecast as a link between these two devices.


The third solution for a wireless connection to the video card Miracast. The premise for this connection that both the projector and the smartphone support this technology (for this reason I recommend you check the data sheet of both products or do a search on Google). The latest generation Android smartphones support almost all Miracast. If the projector does not support this technology, just buy a Miracast adapter for a few euros, connect it to the projector's HDMI port and share the screen of your Android smartphone.
